"It's very important to work your core because it's the foundation. It's the center of the body, and it holds and supports everything else. Also, it's going to help you lean down faster, it's going to give you a better physique, and it's going to reduce your chances of getting injured," he says.

Here are a few of his favorite core exercises:

Lower Abs Plank

1. Start in a plank position.

2. Slowly bend your knees and lightly tap them on the ground.

3. Straighten back to your plank.

4. Continuously draw your abs in.

Repeat for about 30 seconds.

Side Plank

1. Start in a plank

2. Rotate over to your side, stack both feet on top of each other, reach up with the arm that's toward the ceiling.
